SINGAPORE - Singtel's 3G and 4G mobile data services have been fully restored, according to a 5.30pm update on Singtel's Facebook page.
Singtel customers were having difficulty accessing 3G and 4G mobile data services for about four hours on Wednesday afternoon.
Many subscribers left comments on Singtel's Facebook page on Wednesday afternoon, voicing their frustration.
Readers of The Straits Times reported that there was no mobile data in many areas like Bukit Panjang, Tampines, Orchard, Woodlands and HarbourFront.
Others said they could not call through to Singtel's customer service hotline.
Evelyn Wee, 37, who runs an online clothing business: "It really is quite annoying, as I run an online business so I need to always be able to liaise with customers on the go."
Ms Wee noticed the network was down at 2pm after she left her house, where she uses WiFi. Other users say the problem began around noon.
Apparently Singtel's 4G service is down
